# SKSearchResultsFilterCallBack

Deprecated. Use SKSearchCreate and SKSearchFindMatches instead, which do not use a callback.

## Declaration

```swift
typealias SKSearchResultsFilterCallBack = (SKIndex?, SKDocument?, UnsafeMutableRawPointer?) -> DarwinBoolean
```

## Parameters

- `inIndex`: The index you are searching.
- `inDocument`: The document URL object within the index you are searching.
- `inContext`: An application-specified context which you set when calling doc://com.apple.documentation/documentation/coreservices/1448610-sksearchresultscreatewithquery or doc://com.apple.documentation/documentation/coreservices/1448629-sksearchresultscreatewithdocumen.

## Return Value

Return Value A Boolean value of true for a successful search hit, or false otherwise.

## Discussion

Discussion Deprecated. Defines a pointer to a search-results filtering callback function for hit testing and processing during a search. Use this callback function to perform custom filtering on the search hits returned by the SKSearchResultsCreateWithQuery and SKSearchResultsCreateWithDocuments functions. Return true to keep this document URL object (SKDocumentRef) in the results, false to filter it out.
